Male Lower Rank 1 Blood Demon Art: Forced Unconscious Sleep

Male Lower Rank 2 Rokuro likely possesses strength around the level of Lower Rank 3. Seeing as ordinary demons who received Muzan's blood lost their reason and couldn't use Blood Demon Arts but still rose to Lower Rank levels of power, Rokuro—who is much stronger than ordinary demons—might have become as powerful as Enmu if Muzan had given him more blood, as he himself claimed.

Male Lower Rank 3 A demon with slanted eyes and X-shaped scars on his forehead and both cheeks. The number engraved in his eye is Lower Rank 3 (下参).

Female A short-haired female demon with two horns on her forehead. The number engraved in her eye is Lower Rank 4 (下肆).

Male Lower Rank 5 Blood Demon Art: Thread -A technique that weaves and launches threads that ripple in the form of a spider web by bringing both hands together.

Former Lower Rank 6 Blood Demon Art: Tsuzumi -His ability involves tapping the drums (tsuzumi) attached to his body to make the mansion's structure like a maze or move the rooms. He makes the mansion structure a mess, turning floors into ceilings or walls to prevent escape, and is precise enough to separate those in the same area. Each drum has a different ability. The problem is that if a drum falls off his body for any reason and another person or demon picks it up and taps it, they can use the effect as is.

Lower Rank 6 Male

Upper Rank 1 Blood Demon Art: Crescent Moon Blades His most striking physical feature is his six eyes, which chill those who see them. Additionally, his yellow irises are set against sclerae that are stained deep red. Except for the number of eyes and his pale skin, his appearance does not differ much from a human's, perhaps by design. For instance, while the shape of nails varies by demon, Kokushibo's nails are a normal shape, albeit a bit dark, unlike the sharp light-blue nails of Muzan or Doma. Rather, he has an aesthetically pleasing body with a height of 190cm and well-developed muscles from never neglecting his training.

Upper Rank 2 Blood Demon Art: Powdered Ice He is the leader of the Eternal Paradise Cult, a pseudo-religion that serves Muzan Kibutsuji. Among the Twelve Kizuki, he has the most human-like appearance. He is a handsome young man with a sophisticated aura, characterized by a gentle impression, a constant smile, and hair that looks as if the top was drenched in blood. However, he has a major flaw: a complete lack of emotion formed by his innate nature and a life lived outside the bounds of normalcy. Because of this, he lacks social awareness and tact; when the Upper Ranks are summoned to the Infinity Castle, the others, including Nakime, treat him like an outcast and act as if he isn't there.

Upper Rank 3 Blood Demon Art: Destructive Death

Upper Rank 4 Blood Demon Art: Infinity Castle -She manipulates space using the distorted extra-dimensional 'Infinity Castle' with a biwa as her medium. Seeing as the entrances to the Infinity Castle open on the ground from the outside, or conversely, the castle rises from underground to the surface, it seems she created the space using the ground as a medium. Among Blood Demon Arts, it shows the widest range and versatility, with no concrete way to counter it. This Blood Demon Art itself serves as the main stage for the final arc.

Upper Rank 4 Blood Demon Art: Emotion Manifestation -A being that does not die even if his head is cut off. In fact, the more his head is cut, the stronger he becomes.

Upper Rank 5 Blood Demon Art: Summoning He has the least human-like appearance among the Twelve Kizuki. He has a grotesque face with mouths where his eyes should be and an eye where his mouth should be. He has numerous hands like the Hand Demon and a tail instead of legs on his lower body.

Upper Rank 6 Female Gyutaro's younger sister Blood Demon Art: Obi -She freely manipulates sashes (obi) that are harder than steel. Daki's obi, manifested through her Blood Demon Art, appear to be formed from her own musculoskeletal and nerve bundles, similar to the weapons of other Upper Rank demons.

Upper Rank 6 Male Blood Demon Art: Poison Blood, Blood Blades Daki's older brother -He uses dual sickles as weapons and can launch his own blood, which overflows from the sickles, as flying slashes. These slashes can be controlled remotely, so if an opponent dodges, he can change their trajectory to home in on the enemy again. Furthermore, all the blood coming from his sickles and Blood Demon Art is highly toxic, so anyone without a strong resistance to poison will immediately find it difficult to move.

Upper Rank 6 Blood Demon Art: Thunder Breathing -A case where the breathing style itself became a Blood Demon Art upon becoming a demon, like Kokushibo. Unlike Kokushibo, who emits additional crescent-shaped slashes, Kaigaku doesn't project anything outward, but he gained the ability to make the struck area gradually crack in the form of lightning until the body completely collapses.
